A disposable diaper that includes a base sheet and an absorbent panel placed onto the base sheet and provided with pleats defined by folding the base sheet together with the panel in a transverse direction across a crotch regions front zone adjacent to a front waist region and a crotch region's rear zone adjacent to a rear waist region, respectively. Transversely opposite end regions of the respective pleats are joined to side flaps, respectively.
Claims6
A disposable diaper comprising:
- a front waist region;
- a rear waist region;
- a crotch region extending between the front waist region and the rear waist region:
- a substantially liquid-impervious base sheet;
- a liquid-absorbent panel placed onto said substantially liquid-impervious base sheet;
- a pair of end flaps extending in a transverse direction immediately outside longitudinal opposite ends of said liquid-absorbent panel;
- a pair of side flaps extending in a longitudinal direction immediately outside transversely opposite side edges of said liquid-absorbent panel;
- at least one pleat defined by folding said substantially liquid-impervious base sheet and said liquid-absorbent panel together, said at least one pleat extending in the traverse direction across at least one of a front zone of said crotch region adjacent to said front waist region and a rear zone of said crotch region adjacent to said rear waist region, said pleat having transversely opposite end regions thereof joined to said pair of side flaps.
